2.5 LVI Pin.
Discussion Point. The LVI pin is used for the HU to indicate to the DC that a low
voltage event is happening and an abrupt termination of the 3.3V power supply is
expected. T1 is the time for between LVI input is to toggled and when the 3.3V supply
drops to below 3.1V. Visteon desires this to be ≥ 20 mSec, but is it understood this is
not feasible in HU design. LVI pin is pulled low in such a way as to maximize the time
T1 before power supply and or reset line get pulled due to low battery condition at HU
power supply.
Note: Enable and Reset remain high for at least T1 seconds after LVI signal goes low.

4 UART Protocol
The low level protocol is defined in the reference specification 28330 NDS00 AVC
System Comm Spec1.pdf. The HU shall be the AV Unit control station and the DC
shall be the subsidiary machine. The Protocol will be implemented without a physical
layer, and both the DC and HOos shall operate at 3.3V. Both HU and DC shall
implement all features and modes (ie conversation mode) of the protocol as defined. A
maximum Baud rate of 38.4 kbps shall be supported. While in normal operations, the
Baud rate shall be 9600 bps. 38.4 kbps shall be supported for reflash operations.

1. This indicates OS and UART are up and running. If this is not received in T1 seconds, HU should strobe reset line again.
2. When the HeartBeat.HeadUnit is received by the DC, the DC start the Vehicle Config sequence. DC will continue to send
HearBeat.BTCard messages to the Head Unit until a reply is sent.
3. The default configuration will be Panasonic if the value for Head Unit ID in the Vehicle.Config.Set message is undefined.
4. If the Language Change sequence is run, the Initialization time will increase by up to the maximum time called out in the sequence. This
needs to be added to the T2 time as it will increase the time it takes for the DC to be fully initialized and ready to be used.
5. Only after FullRun is sent will the DC be able to accept any button press messages. All button press messages will be ignored before this.
6. These messages are for the Panasonic DA only
Notes:
The Language Change sequence has been removed from the Initialization Sequence. If a Language Change is called during Initialization,
then the timing to be fully initialized and ready for button presses will increase by the Language Change timing.
Heartbeat messages are sent continuously throughout the operations of the DC.
The HU should not work off of the number of HeartBeat messages received during start up. The time out is to be used to determine the state
of the DC during initialization.
T1 = TTimeToBootToFirstHeartbeatMessage = 15 seconds.
The maximum time it will take the DC to boot up to send the first HeartBeat message (From the time that power is applied, the Enable line
asserted, Reset and LVI not asserted). If this time is exceeded, it is expected that the HU will reset the DC and perform the Mismatched Baud
Rate sequence as
T2 = TTimeToFinishInitAfterFirstHeartbeat= 6 seconds.
The maximum time it will take the DC to report that it is in the Full Run state and can begin to process button presses. If this time is exceeded,

The BTHFU receives from the paired phone the number of available bars and the
number of active bars.
The algorithm to determine the percentage (%) of power is active bars / available bars.
Example: A paired phone has a total of 5 available bars of which 3 are active. The
percentage is calculated as:
Percentage = (3 / 5) * 100 = 60%

Sequences
o The following information is the detail that is missing from the MCAN Sequence Spec IT Master – Meter
that is provided by Nissan. Please use the Spec IT Master in conjunction with these rules below.
Meter General Rules
Any meter messages that also have a head unit comparable message, they should be sent is
succession to each other so that the visual cue from the User will appear that they appeared at the
same time.
o The HF, VR and SMS messages required an State=End message to dismiss this message from the
meter. SMS and HF messages can cover the VR message. When the HF or SMS message in front of it
is ended, the VR message can still be present unless it is ended also.
o Audio Warning messages do not have an End message and are just sent when required. No further
management of them is necessary.
o Disc messages do not have an End message. They are sent and the Meter will handle their display
lifetime.

MCAN Disc Messaging
o If one of the fields in the Disc message is updated, the entire message needs to be resent with all of the
information that is available about the track even if the Update value for that text tag is “Not_Updated”.
Track updates are natural non-user actions. Therefore Interupt shall be set to Disabled.
o Disc message will not be sent periodically except for the reasons in the requirement for Scan and
FF/Rew.
o Scan, FF/RW and Track Up/Down
ƒ
Require an update at a 1 second rate. This message will contain all of the information about
the track every time.
Track, FF/RW, Scan will always have the Interrupt set to Enable. These are user directed
ƒ
activities.
ƒ
During a FF/RW session, if the track changes before the next one second update occurs, then
the DC shall send an updated Disc message (Event) with the updated track information. The
one second cyclic timer is restarted from the Disc Event message.
ƒ
When a new track number is set, only the Track Update parameter shall indicate 0x01 Updated.
ƒ
The Group and Artist Update parameters shall stay at Not_Updated even if the information
has changed for these strings.
The message shall include the new information for Group and/or Artist.
ƒ
ƒ
o Natural song changes due to the end of songs or other Non-User initiated activities, the Interrupt shall
be Disabled.
o The XXXX.Update field shall indicate what parameter is updated in the message. Even though other
parameters may not be updated they shall all be sent.
o When the Interrupt is Disabled, all XXXX.Update parameters shall be set to 0x00 – Not Updated.
o Sequences not followed are:
ƒ

12-7
ƒ
12-8
ƒ
12-10
ƒ
12-11
12-12
ƒ
12-15
ƒ
12-16
ƒ
o 12-1: The HU has changed to BT Audio
ƒ The HU will send this message with the default values in it shown on the sheet before the DC
when the BT Audio. The HU will handle the negotiation of the messages.
ƒ
DC message shall be sent these values unchanging:
1. Interrupt
= Enable
2. Disc_Source
= 0x05h – 00000101 for Audio/ BT-Audio.
3. Text Info Char set
= 05h – UTF-8.
= 05h – UTF-8.
4. Group Char set
5. Artist CharSet 1 byte = 05h – UTF-8.
ƒ The BT shall send an updated message with Song data when it becomes available.
o 12-2: Change of Disc Source
ƒ
This is handled by the sequence in 12-1. When BT Audio is selected, the behavior in 12-1 is
executed by the DC. When the HU changes to another audio source, the DC shall NOT send
any disc messages.
o 12-5: Track Up/Down. This message is sent when the track is changed by a user action.

UART 5.9 SMS Message Sequence, message read
This is probably already in the software but needed to be included for clarity.
Added two sequences to deal with:
UART 5.20 SMS Sequence while the DC is in a Setting Screen
UART 5.21 SMS Sequence wile the DC is in an Active Call
10.2.6 CQ 27267 config error behavior incomplete
Defined Rest of Bits in config.set message for HU to inform DC which HU it is, and defined DC behavior for all
possibilities.
